Z-330P2J
ADSL over POTS CPE In-Line Filter
Description
The Z-330P2J is a small, in-line, ANSI T1.421-
compliant customer premise equipment (CPE)
filter designed to expedite the service delivery
and improve the performance of asymmetric
digital subscriber line (ADSL) and home
phoneline network (HPN) services over plain
old telephone service (POTS). The Z-330P2J
filters all telephones, facsimile (fax) machines,
answering machines, and other telephone
equipment. Its third-order filter design
electronically isolates the high-speed ADSL and
HPN data streams from the voice-band POTS to
provide premium voice quality and optimal DSL
and HPN data rates.
